To all whom it may concern:

- which the following is a specification.

- onnsrnn and JOHN BURTON United States, residing at lirockton, in the Th 4 Be it known that we, COLEMAN S. WIN- citizens of the unty of Plymouth and State of Massa ;chusetts ,have invented new and useful Improvements in Door and Window Screens, of The object of this invention is to provide a screen, the frame member of which is constructed to releasably confine the woven wire member in such manner that the wire member, when rendered, veiniently removed and replaced by a fresh member, by a person unskilled in the art of nhailing'the wire member to the frame mem- 13: I The invention isembodied in the improvements hereinafter described and claimed.

Figure 7 is a side elevation of a window 1 screen embodying the invention.

Fi re 8 is a fragmentary perspective sectiona view, the section being on line 8-8 of Figure 7.

Figure 9 is a section on line 9-9 of Fi ure 7.

iigure 10 is a side view of one of the spurs shown by Figures 2, 5, 6, and 8.

Figures 11 and 12 are views similar to Fi re 9, showing modifications.

fie same reference characters indicate the same rts in all of the figures.

Re erring first, to Figures 1 to 6, inclusive, showing theinvention embodied in a screen door, 12 re resents an inner frame section of rectangu or form. Projecting from one Of the side faces of the section 12 are metal spurs 13, adapted, as shown by Figures 4 and 6, to engage meshes in the marginal portion of a filling sheet 15. The spurs are useless, may be conpreferably hook shaped at their outer-ends and may be of wire, and drawn into'the section 12 with their hooked ends projecting. e spurs are so 'formed and arranged that the sheet 15 may be conveniently impaled thereon, and held thereby against the side of the section, the hooked form of the spurs causing the outer ends to overhang the sheet, so that the sheet is not liable to slip oil from the spurs when the inner section 12 is being handled to engage it with the outer frame section hereinafter described.

16 represents an outer frame section, which in this instance, is the frame or body portion of a screen door adapted to cooperate with a plurality oi inner. framesections 12, each of which constitutes a panel, occupying an opening in the body or outer frame 16. The said inner frame sections are duplicates of each other, so that the part 16 will be hereinafter referred to as an outer frame section, cooperating with an inner frame section 12. The outer frame section 16 has an opening 17 (Figure 3) which re ceives and closely fits the margin of the inner section 12, and a flange 18, surrounding the opening li', and projecting inward from the margin thereof. The inner side of said the sheet 15 against the face of the inner section from which the sp ms 18 project. The flange 18 may be attached to the outer frame section 16 by nails or screws, or by any other suitable means. The inner side of the flange 18 is recessed at 19, to receive the projecting portions of the spurs 13,'as shown by Figure 2. We provide means for detachably securing the inner section 12 to the outer section 16, said means being embodied, in this instance, in an outwardly projecting flange 20, attached as by screws 21 to the inner section 12, and overlap ing the outer section, and screws 22 attac ing the flange to therouter section.

In assembling the described parts, the o eretor first engages thesheet 15 with t e spurs 13, then inserts the inner section in the opening in the outer section until the marginal portionof the the seat formed by the flange 18, and the outer ends of the spurs enter the recess 19.- The screws 22 are then driven and confine the inner section and the'sheet 15 in place sheet is pressed against in the outer section. When the sheet 15 re-,

bodiment 25 represents the inner frame section from one side face of which project aaaaeaa Figures 11 and 12 show modified forms of the spurs, Figur 11 showing a straight spur 13, driven obliquely into the inner so that it is the equivalent of a frame section, a hooked spur. Figure 12 shows a straight spur 13", standing at right angles with the face from which it projects. The hooked form is preferred, because it prevents the sheet 15 spur.

We claim: L'A'screen frame comprisin an innbr frame section having screen'clot -engaging spurs rojecting from its inner side face, the spurs ing adapted to engage meshes of a the s ms 13. The outer frame section 26 foraminous sheet, an outer frame section is re ated, as shown by Figures 8' and 9, which is rebated to receive the inner section to receive the inner section 25, and and form a clamping face, adapted to conform a seat 27, between which and. the fine the marginal portion of a sheet of inner section 25 the marginal portion of the screen cloth against the inner side of the sheet 15 is clamped. The outer section 26 is recessed at 28 ,to receive the spurs 13.

To detachably connect the sections 25 and 26, we provide sheet metal clamping members, bestridin and frictionally enga ed with the assemb ed'se'ctions, as shown by igures 8 and 9, and adapted to run with the screen in the usual screen guides in a window frame. As here shown, these clamping members include two U-shaped members 30, embracin portions of the frame between its ends, an two elongated members which are slidable on the end portions of the frame and constitute adjustable extensions wherel) the length of the frame ma be varied. ach of said elongated mem ers includes a central portion 31, extending across the frame, and bearing on one side thereof,

neck portions 32 at theopposite ends of the central portion, ears 33 connected with the central portion by the neck ortions, and a stop flange 34, formed on t e central portion and adapted to abut against the end of the frame.

Each of the said clamping members frictionally engages the frame with suflicient force to move therewith, and is adapted to be removed to permit the separation of the frame sections.

2. A screen frame comprising an inner frame section having screen cloth-engaging spurs projecting from its inner side face, the spurs being adapted to engage meshes of a foraminous sheet, an outer frame section which is rebatd to receivethe inner section and form a clamping face, adapted to confine the marginal portion of a sheet of screen cloth a inst the'mner side of the inner section,

ceive the projecting portions of said spurs, and sheet metal clamping members detachably connecting said sections, and adaptedto run therewith in guides in a window casing, two of said clamping members being slidable on the end portions of the assembled sections, and formed to constitute adjustable extensions thereof.

In testimony whereof we have afiixed our signatures.
